How Slab Leak Detection in Paramount, CA Is Done
Booking slab leak detection in Paramount, CA gets you a full test sequence, not a quick listen and a shrug. These are the steps.
- 01
Meter and leak-dial check
Every fixture off, then the meter dial is watched. Movement with the house silent means water is going somewhere it shouldn't.
- 02
15-minute pressure-gauge test
- 03
Hot or cold isolation
The water heater supply is closed to see which side is leaking. Hot leaks warm the floor; cold ones do not, which is why they need this step.
- 04
Branch isolation
- 05
Acoustic pinpointing
Ground microphones listen through tile, carpet and concrete for the sound of water escaping under pressure.
- 06
Thermal imaging
- 07
Marked location and options
